When doing an upgrade from Lion on a 2012 MBP with an SSD as main drive and HDD in OptiBay, are the symlinks for user folders like Documents, Music, Pictures, Downloads, etc preserved without issue? Specifically, I have my data files on the HDD like many here with symlinks on the SSD in the user's folder to the HDD and want to know if that will cause any problems or require extra steps when going the upgrade path?
